摘　　要：植物细胞中叶绿体的功能主要依赖于叶绿体蛋白,大部分叶绿体蛋白由核基因组编码,在细胞质中合成并经过正确的分选后,通过叶绿体外膜上的Toc复合体和/或内膜上的Tic复合体转运到叶绿体的不同部位。该文主要综述可能参与叶绿体蛋白分选的胞质因子以及Toc和Tic组分如何参与叶绿体蛋白转运的研究进展。Chloroplast function largely depends on chloroplast proteins in the plant cell; most chloroplast proteins are encoded by the nuclear genome and are transported to the chloroplasts after translation in the cytosol. The proteins needed to be correctly sorted in the cytosol first, then targeted to various compartments of the chloroplasts by the translocon at the outer envelope membrane of chloroplasts（Toc） complex and/or the translocon at the inner envelope membrane of chloroplasts（Tic） complex. This review focuses on cytosolic factors possibly involved in sorting chloroplast proteins and how Toc and Tic components translocate chloroplast proteins.
